But eight tickets are left to be punched.

What to Watch For

Mercer, Tennessee Eye Cinderella Run

A day after No. 11 Dayton punched its ticket to the Sweet 16, No. 14 Mercer and No. 11 Tennessee will go head-to-head in a battle of Davids.

The experienced Bears won the Atlantic Sun Conference this March and start five seniors. And after knocking off the third-seeded Duke Blue Devils on Friday, Mercer will enter Sunday night's showdown with tremendous belief that it can march on.

Even in defeat, Duke head coach Mike Krzyzewski had no choice but to praise the Bears' experience, per The Washington Post's John Feinstein: "They’re men. They’re strong, and I don't just mean physically. They have a great coach. Honestly, what they did was beautiful to see. I applaud them and I applaud their fans for what they've done this season."

However, the Volunteers will be awfully tough to beat after winning two tournament games already. Tennessee, who knocked off No. 11 Iowa in Round 1 and No. 6 Massachusetts in Round 2, will be a 7.5-point favorite in this matchup and should have plenty of crowd support while playing in Raleigh, N.C.

The squad that fares better on the glass will likely decide the outcome. Both teams rank inside the top 40 nationally in rebounds per game, but Tennessee is among the best rebounding teams in the country, pulling down roughly 39 per contest.

Led by Jarnell Stokes, the Volunteers crushed the Hawkeyes on the boards, 37-30, and out-rebounded the Minutemen as well, 37-33. If Stokes and company can secure a few offensive rebounds and limit Mercer's second-chance opportunities on the other end of the floor, Tennessee will be marching on.

Stephen F. Austin Is Playing with House Money

The Stephen F. Austin Lumberjacks have won 29 straight games after breaking fifth-seeded VCU's heart in the second round on Friday.

Trailing by four points late, the Southland Conference champions converted on a four-point play to force overtime. The Lumberjacks would prevail in overtime, setting up a third-round meeting with No. 4 UCLA. The come-from-behind win was so spectacular that it even earned a shout-out from former Texas Longhorns football coach Mack Brown:

Congrats to SFA. Great comeback. What a deal! Good luck moving forward

But SFA still has a lot of work left to do in order to reach the tournament's second week. The Lumberjacks will be nine-point underdogs in San Diego and are set to face a high-scoring Bruins team that moves the ball well and can make shots from anywhere.

Meanwhile, Mark Few's Bulldogs are coming off an impressive win over Oklahoma State, whom many considered a dark horse before the tournament started. Gonzaga, who ranks fifth in the country in team field-goal percentage (49.8 percent), has now won six straight games.

Three No. 1 seeds will be in action on Sunday, but it appears that Arizona is the one most likely to fall victim to an upset. Nonetheless, the Wildcats will be 6.5-point favorites in San Diego.
